Despite recording some landmark works with GRM (including a masterful triple LP with Pierre Schaeffer in the '60s), Guy Reibel is a name that is often forgotten when discussing musique concrète. While fame (as far as fame for experimental 20th century composers goes) has eluded him compared to other members of the GRM, his music has always delivered. This album, originally released in 1978, shows Reibel in particularly good light as he creates an unprecedented, and since unmatched, sonic vocabulary.
